SPECIFICATION forming part of Letters Application filed August 5 1898 To all whom it' may concern,.-

Be it known that I, NOAH G. I-IUrFsrIcK-Yv LER, a citizen of the United States, :residing at Mount Holly, in the county of Gaston 5 and State of North Carolina, have invented a new and useful Roping-Guide for Spinning- Frames, rite. of whichthe following is a speciication.

My invention relates to roping-guides for 1o spinning-frames, draw-frames, and like machinery; and the object that I have in view is to provide a mechanism by which strands of yarn are perfectly twisted by subjecting the same to equal and uniform pressure and 15 keeping them at equal distances on opposite sides of a saddle and moving said strands in opposite directions simultaneously for uniform distances.

The invention consists in the novel combizo nation of elements and in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

To enable others to understand my invention I have illustrated the preferred embodiz 5 ment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a side elevation of a portion of a pair ot' drawing-rolls with my improved 3o yarn-guide in operative relation thereto. Fig. 2 is a vertical transverse sectional view of the same on the line tr @cof Fig. 1. Fig. Sisadetail sectional view on the line @j y of Fig. 1.

Like numerals of reference denote like and 35 corresponding parts in each of the several figures of the drawings.

A setjof ordinary drawing-rolls is indicated by the numeral 1 in the drawings, and said set of rolls includes a steel roll 2 and a yield- 4o able roll 2, which has its working surface formed by a covering of leather or other suitable material.

3 is a saddle of ordinary construction arranged in a groove 3a, provided in the steel Below the set of rolls is a fixed stand 4L, which carries a horizontal frame 5, arranged to support the operating devices by which the yarn-guides are moved in opposite directions Patent No. 635,686, 'dated october 24, 1899.

simultaneously. As shown by the drawings, this horizontal frame is constructed with the outwardly-extending pairs of arms 6 and 7, and these arms are formed at their free ends with the upper pair of guides 8 and the lower pair of guides 9. The guides 8 on the upper arm 6 are arranged in line with each other to accommodate a driving rack-bar, while the guides 9 are provided on the lower arm G of the frame, so as to lie in the same horizontal plane vand receive another reciprocating rack-bar, Awhich is driven simultaneously with and in an opposite direction to the driving rack-bar by suitable gear connections between the two rack-bars, as will presently appear.

`The yieldable roll 2a of the set of drawingrolls is provided or formed with a worm 10 in the vertical plane of the recess or groove in the upper roll. 2, and lwith this worm meshes a worm-gear 1l, which is arranged below the roll 2a and is journaled on the horizontal shaft or arbor suitably supported in the stand 4, whereby the worm-gear is driven from the roll 2 of the machine. The worm-gear is formed with a hub or sleeve 13, which is extended a suitable distance therefrom and occupies a horizontal plane between the upper and lower arms or guides of the frame 5, and on this sleeve or hub are mounted a drivingcam and a gear-pinion. The cam is shown by Fig. 1in the form of a heart-shaped cam, and it is rigidly fastened in any suitable way to the sleeve or hub of the worm-gear to rotate therewith.

In the guides 8 of the upper pair of arms 6 is slidablyiitted a driving rack-bar 15, which is free to move in a horizontal direction transversely across the shaft or arbor 12 and in a plane parallel to the axis of the `rolls 2 2a, and in its lower edge this rack-bar is formed with a series of teeth arranged to mesh with the idle or loose pinion presently described. The rack-bar 15 is positively driven or reciprocated by the heart-shaped cam 14, and to this end- I provide a pair of arms 1G, which are disposed on opposite sides of the cam and are rigidly attached to the rack-bar 15 by screws or other suitable fasteners. v The arms 16 of the driving rack-bar are provided at their lower ends with friction-rollers 16, which are loosely mounted in said arms 16 and are arranged to ride against the edge of said cam 14E, and as the cam is rotated by the wormgear it imparts the reciprocating motion to the rack-bar 15.

In the guides 9 of the lower pair of arms 7 on the stand-frame is slidably fitted a rackbar 17, and on its upper edge is provided a series of rack-teeth which are opposed to the similar teeth on the driving rack-bar 15. The lower rack-bar 17 is driven from the rack-bar 15 by the idle gear-pinion 18, which is mounted loosely on the hub or sleeve of the wormgear 11, and as the bar 15 is driven in one direction by the heart-shapedcam the pinion 18 is rotated by said bar 15, so as to actuate the bar 17 in an opposite direction to the movement of the bar 15. Said bars 15 17 are thus connected by the gear-teeth and pinion to move in opposite directions simultaneously, and as the bar 15 is driven in one direction by the cam the other bar 17 is moved in the opposite direction by the idle gear-piuion, and vice versa.

The yarn-guides through which the strands of yarn are carried and twisted are supported by slidable carrier-bars, which are fastened to the respective rack-bars 15 17, and these carrier-bars are arranged substantially parallel to rolls 2 2a and rest one upon the other, substantially as shown by the drawings. One of these carrier-bars (indicated at 19) is joined or fastened to the carrier-bar 15 by means of an arm 20, rigidly fastened to the bars 19 and 15, and the other carrier-bar 21 is secured in like manner to the other carrier-bar 17 by an arm 22. The carrier-bars 19 21 are arranged to reciprocate or travel with and to be impelled by their respective rack-bars 15 17, so that the carrier-bars reciprocate in opposite directions simultaneously. These carrierbars sustain the yarn-guides 23 23, which are fastened, respectively, to the vbars 19 21, as shown by Fig. 1, and these yarn-guides are disposed on opposite sides of the worm and the saddle, so that they lie at equal distances therefrom.

The several working elements of the mechanisin for actuating the yarn-guides are so proportioned as to impart an equal movement or play to the carrier-bars 19 and 21, and thus the yarn-guides are adapted to move in opposite directions for equal distances from the saddle. I attach importance to the means whereby the yarn-guides are moved in oppo site directions simultaneously, and an equal traveling movement is given to said guides, so that they are maintained the same distance from the saddle throughout their traveling play toward and from the same, and this arrangement and adaptation is advantageous in that equal pressure is maintained on the strands of the yarn or rope to insure proper twisting of said strands.

It is thought that the operation will be readily understood from the foregoing description, taken in connection with the drawings.

Changes may be made in the form of some of the parts, while their essential features are retained and the spirit of the invention embodied. Hence I do not desire to be limited to the precise form of all the parts as shown,

reserving the right to vary therefrom.

Having thus described the invention, what I claim is- 1. The combination with drawing-rolls, of a driving-gear carrying a cam which is fast therewith and an idle gear-pinion, rack-bars meshing with said gear-pinion and movable in opposite directions simultaneously, means carried by one rack-bar and engaging with the cam to be actuated thereby, and guides or travelers connected operatively with said rack-bars, for the purpose described, substantially as set forth.

2. The combination with drawing-rolls, of a drivin g-gear meshing with one of said rolls and having a hub or sleeve, a cam mounted on said hub and fast with the gear to rotate therewith, a rack-bar provided with the roller which engages with the cam and is actuated thereby, a gear-pinion mounted idly on the hub of the driving-gear and meshing with the rack-bar, another rack-bar disposed on the opposite side of and meshing with said idle gear to be actuated thereby, and guides or travelers connected operatively with said rack-bars, substantially as described.

.3. The combination with drawing-rolls, of a worm-gear, a cam rotating said worm-gear, a rack-bar actuated directly from the cam, another rack-bar driven by'an intermediate gear from the first-named rack-bar, carrierbars connected with the respective rack-bars, and yarn guides or travelers mounted on the carrier-bars, substantially as described.

t. The combination with drawing-rolls,and carrier-bars united With the yarn guides or travelers, of a worm-gear driven from one of the rolls and having a sleeve or hub, a cam fitted to the sleeve or hub to rotate with the worm-gear, a driving rack-bar arranged to be reciprocated directly from the cam, another rack-bar, a driving-gear mounted loosely on the hub or sleeve and meshing with both rackbars, and means for connecting the carrierbars with the respective rack-bars, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses. f NOAH G. IIUFFSTICKLER. Witnesses:
